Allen-Bradley 140M-D8N-B63 Circuit Breaker

The Allen-Bradley 140M-D8N-B63 (140M-D8N-B63) is a circuit breaker designed for electrical protection and switching within industrial control architectures. Operating as part of Allen-Bradley power distribution and automation assemblies, this protective component safeguards connected downstream hardware, electrical equipment, and motor branch circuits against overcurrent and short-circuit conditions. It plays a critical role in maintaining system integrity, operational safety, and continuous plant uptime across automated machinery. Built for heavy-duty industrial environments, this unit features a durable construction with a net weight of approximately 10 kg, making it suitable for panel mounting within motor control centers, control cabinets, and distribution switchgear. It provides reliable isolation and interruption during electrical faults, helping prevent equipment damage and costly production stoppages. The unit integrates seamlessly into industrial automation setups across manufacturing lines, material handling systems, assembly machinery, packaging plants, and industrial processing facilities. Technicians and system integrators can deploy the device for routine maintenance, system upgrades, or direct hardware replacement to ensure consistent operational safety and compliance across demanding industrial automation applications.
